Application led November 6, 1909. Serial No. 526,556.-

To `oZZ whom 'it may concern: e

Be it known that I, CLINTON Anno'rr, a citizen of the United States,residing at Zinc, in the county of Boone und State of Arkansas, haveinvented new and useful Improvements in Can-Openers, of which thefollowing is a specification.

Thisinvention relates to that class of can openers that are adapted toopen cylindrical sealed cans by cutting an approximately circular pieceofthe tops thereof, and the invention has for its object to provide amachine of simple and inexpensive construction which ma be easily andquickly manipulated to e'iiect the desired result.

A further object of the invention is to provide a machine of the classindicated which may be readily adjusted to operate upon cans ofdifferent sizes and diameters.

Further objects of the invention are to simplify and improve theconstruction and 4 operation of this' class of machines.

With these and other ends in view which will readily appear as thenature of ythe invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being however understood that no limitation isnecessarily made to the precise structural details therein exhilnted,but thatj changes", alterations and modifications within the scope ofthe invention may be resorted to when desired.

In the drawings: Figure 1 is a side elevation of a can openingmachine'constructed in accordance with the invention. Fig. 2 is aVertical sectional view of the same. Fig. 3 is a top plan view of themachine somewhat enlarged. Fig. 4 is a horizontal sectional view,enlarged, taken on the line 4-4 in Fig. 1. Fig. 5 is 'a sectional detailview taken on he plane indicated by the line 5-5 in Pig. 2.

Corresponding parts in the several figures are denoted 'by likecharacters of reference.

'lhe frame of thc'improved machine comprises a. pair of uprights whichfor convenience will be deseri-'nsd as the front and rear uprigbts (3and 7; .the same being mounted upon a base 8 and connected-at theirupper ends by a bridge piece or cross piece 9. The rear upright isprovided with a transverse slot 10 intersected by a longitudinal slotll;extending through, 4and vertically adjustable in the transverse slot 10is a clamping screw 12 having a wing nut 12 and serving as a pivoterfulcrum' for a lever L which is free to operate in the' slot l1, saidlever being provided at its front end with a handle 13. The lever Lextends through a. slot 14 formed in the front upright 6, said slotbeing provided upon one of its side walls withteeth -or ratchets 15 withwhich the lever may be placed in engagement, by slightly tilting saidIlever which may thus be retained in position at various adjustments.Pivotally mounted in thc slot 14 near the lower end of the -latter is anarm 1G which is connected with the lever L by means of a link 17; ashank 18 that extends through an aperture in the arm` 16 carries at itsrear end a gripping jaw 19 having a curved serrated face 20. matinggripping 'jaw 21 is formed upon a shank 22 'that extends from therearupright 7 with which it is se= curely connected. An auxiliary grip ingjaw 23 correspondingr with and locate in the vertical plane of the rearjaw 2l is secured upon the base 8 directly below `said jaw 21. l

The top piece or bridge piece 9 of the frame is provided with alongitudinal slot 24 and a corresponding slot 25 1s formed in a slide 26which is secured adjustably upon the bridge piece by means of a setscrew 27 operating through the slot 25. The slide 26 affords a bearingfor a vertical shaft 28 having at its upper end a crank29 .whereby itmay be rotated. The shaft 28 extends through the slot 24 in the bridgepiece 9 and through a slot 30 in the lever. L. The lower extremity ofthe shaft 28 carries a cutter head 31 abuttin u on the underside of thelever L and the s a t 28 is provided with a sleeve-or collar 32 adjacentto the upper side of the leverwith which the shaft 28 is thus op fulcrumof the lever. The cutter head 3l terminates at itslower extremity in aconical point or prong 33; and said head is provided with a transverseslot 34 wherein a shank 35 having a downwardly extending cutting blade36 is adj ustably securedf by means of-a set screw 37.

cratively connected for rotation and for adjustment at various distancesfrom the The shank 18 carrying the gripping jaw 1.9 is mountedadjustably in the arm 16 by Ineans of a set screw 38.

From the foregoing description, taken in' Adjustment of the machine tooperate upon cans of various heights and diameters may be had byvertically adjustinur the fulcriun i. member l2 of the lever L, byxiongitudinally adjusting theshank 18 carr mg the gripping jaw 19, andby laterally a justing the slide 26 which forms the bearing for theshaft 28 carrying the cutter head. After proper adjustment of the partsofthe machine, the can is placed in position upon the base between theripping jaws; by depressing the handle of t ie lever L, the jaws will becaused .to firmly grip the can, and at the same time the cutter headearryinw shaft will be depressed until the top of tie can is punt-.tured by the prong-33 and by the blade 3G. The pron(r 33 serves tosupport the lower end of thel siat't while the latter is being rotatedby the crank 29, thus causing the top of the can to be cut out by theblade or cutter 36.

Having thus described the invention, what is claimed is l.. In a canopeningmachine, a .frame comprising two uprights and a bridge piececonnecting the same, said uprights being provided with slots, a fulcrummember vertically adjustable in a slot in one upright, a lever pivotedupon said fulcrum member and guided through a slot in the other upright,a shaft carried by the lever and having a crank at one end, and acutting device at the other end, a gripping jaw connected With oneupright, an arm pivoted upon the other upright, a gripping jaw having ashank adjustably engaging the pivoted arm, and a link connecting thelatter with the lever.

2. In a can oaening machine, a frame, a longitudinally slotted lever,adjustably con-V nected with the frame, acutter carrying shaft extendingthrough the slot in the lever and through a corresponding slot intheframe, means connecting the shaft with the leverfor vertical movementtherewith, and a slide adjustably connected with the frame and affordinga bearing for the cutter carrying shaft.

3. In a can opening machine, a frame in cluding a. longitudinallyslotted bridge member7 a lever adjustably connect ed with the frame andhaving a longitudinal slot, can gripping means connected with andactuated by the lever, :1y shaft. extending through the slots in thelever and in the bridge piece of the frame, a cutter head u on the shaftabutting upon the underside ot the lever, a sleeve upon the shaftabutting upon the upper side o the lever, and a slide adjustably mountedupon the bridge member of the trarne and affording a bearing for the.cutter carrying shaft.

ln testimony whereof I ailx my signature in presence o tl two witnesses.

CLINTON ABBOTT.
